Adjustable flyer-grinding device



Patented May 13, 1930 PATENT OFFICE ALBERT 1V1. GUILLE'I, OF CHARLOTTE, NORTH CAROLINA ADJUSTABLE FLYER-GRINDING' DEVICE Application filed November 11, 1927. Serial No. 232,624.

My invention relates to a machine for grinding repaired flyers for roving frames after the same have been built up about the worn portions through a welding process de- 5 scribed in a copending application.

An object of my invention is to provide a machine for grinding the exterior of tubular members and comprises holding means for the tubular member and means operated by the 10 individual using the machine for feeding the tubular member to the grinding device.

It is common knowledge that fiyers for roving frames, which have a tubular leg and a solid leg, will wear around the tip end of 15 the tubular leg on acount of the fact that the presser has its bearing portion located around the tip of the tubular leg, and when this tip becomes worn through on one side it is necessary to either repair the leg or discard the flyer, and by welding material on to the worn portion and then grinding this welded portion down to a smooth surface a new bearing portion is provided for the presser.

Some of the objects of my invention having been stated, other objects will appear, when taken in connection with the accompanying drawings, in which Figure l is a plan view of my grinding machine;

Figure 2 is a side elevation of my device,

looking from the left in Figure 1;

Figure 3 is a front end elevation of my grinding machine;

Figure 4 is a view of the pin for holding the member in position while the same is being ground;

Figure 5 is a side elevation of the crank arm on which the holding means are mounted.

Referring more particularly to the drawings, the numeral indicates the base portion, and upon this base portion the electric motor 11 is mounted, which motor has the extended shaft 12 extending therefrom, which shaft extends through a bearing in the upstanding projection 13, the lower end of the projection being secured to the member 10 and on the end of the shaft 12 there is mount ed the grinding Wheel 14, which wheel is secured in place in the conventional manner.

53 The U-shaped projection 15 is secured to the base member 10 and in this U-shaped projection the bell crank lever 16 is pivotally mounted by means of a pin projecting through the hole 17, and in the upper end of the bell crank v lever 16 there is secured the member 18 by L5 means of the nut 19 being secured on the smaller end thereof and the other end of the member 18 has the pin 20 projecting therefrom whicn is adapted to receive the hollow leg 21 of a flyer for spinning frames while 31) the same is being ground. Intermediate the upper end of the bell crank lever and the hole 17, thereis provided the hole 22, in which the member 23 is mounted, which member 23 extends outwardly and around the grinding member lei and on the outer end thereof is secured the upwardly projecting member 2 1 by means of a set screw 25 and in the upper end of the member 24 is the hole 26, in which hole the leg 21 is adapted to slide and be held in position for grinding The bell crank lever 16 has the laterally projecting portion 27 and in the end of the portion 27 is secured the member 28 which extends downwardly and is connected to a pedal 29 which is pivotally mounted as at 30 to the floor of the building in which the machine is operated or to any other suitable support Penetrating the base member 10 and threadably engaging a hole therein is the bolt 31 which has a nut 32 threadably engaged by the bolt and resting against the upper side of the base member 10 and loosely mounted on the upper end of the bolt 31 is the coiled compression spring 33 which is adapted at all times to normally hold the arm 27 in raised position together with the pedal 29.

' The solid leg of the flyer is indicated by the numeral 34': and the grinding member 1% is small enough to permit the leg 34 to be p swung entirely around the grinding member 14 so that the entire surface of the tip of the leg 21 may be ground.

In operation the tubular leg 21 of the flyer is repaired by welding the worn tip thereof which leaves the tip in a roughened condition, and while the flyer is in this condition the tubular leg of the flyer is inserted into the hole 26 and slid around the pin 20 and while the fiyer is in this position as is shown in Figures 1 and 2, the operator presses on the pedal 29 and the end 27 of the bell crank lever 16 is depressed and the tip of the tubular leg portion 21 of the flyer is pressed into engage ment with the rotating grinding wheel i l and while the said portion 21 is in engagement- With the grinding wheel. la the operator rotates the flyer, using the leg 21 as a pivot and in this manner a circular smooth surface is imparted to the welded tip of the leg 21, and by means of the pedal 29 and asse ciated parts the pressure applied can be regulated as desired by the operator.

In the drawings and specification, I have set forth a preferred embodiment of my invention and although specific terms are'employed, they are used in a generic and de scriptive sense only, and not for purposes of limitation, the scope of the invention being set forth in the appended claims.

I claim:

1. In a grinding machine, a base portion, a rotary grinding implement, mounted on said base portion, a bell crank lever pivotally mounted on said base portion, a perforated member supported by said bell crank lever, a pin on the upper end of said bell crank lever located in alinement with the perforation in said perforated member, said perforation and pin being adapted to receive a tubular member, and means for swinging the bell crank lever to bring the tubular member in contact with the grinding means.

2. In a grinding machine, a base portion, an electric motor mounted on said base portion, rotary grinding device driven by said electric motor, a bell crank lever mounted on the base portion, an outwardly projecting member secured on said bell crank lever, an upwardly projecting member secured on said outwardly projecting member, a hole in the upper end of the upwardly projecting memher, a pin supported by the upper end of the bell crank lever, said pin being in alinement with the hole in the upwardly projecting member, said hole and said pin being adapted to receive a tubular member, means for swinging the bell crank lever on its pivot to bring the tubular member into engagement with the rotary grinding device, said means permitting the tubular member to be rotated during the grinding operation.

3. In a grinding device for flyers, a base portion, a motor mounted on said base portion, a circular grinding device mounted on said motor, a bell crank lever mounted on said motor, means associated with said bell crank lever for holding the tubular leg of the flyer at two separated points along the leg of the flyer, means for moving the bell crank lever to force the tubular leg of the fiyer against the circular grinding device, said means being adapted to permit the other leg of the fiyer to be turned completely around the grinding device.

4. In a grinding machine for flyers, a motor driven grinding member, a holding device having means for holding one leg of the flyer at two separated points on said leg, means for pressing the said leg against the grinding device, said holding means being adapted to permit the other leg of the flyer to be completely turned around the grinding device.

5. In a grinding machine, a base portion, a rotary grinding device mounted on said base portion, a bell crank lever having means therein for holding a flyer at two separated points, means for pressing the flyer against the grinding device, said means permitting the flyer to be turned during the grinding operation.

In testimony whereof I afix my signature.

ALBERT M. GUILLET.
